Acar has a mass of 1.00 × 103 kilograms, and it has an acceleration of 4.5 meters/second2. what is the net force on the car?

a.0.9 × 103 newtons
b.2.5 × 103 newtons
c.4.5 × 103 newtons
d.9.0 × 103 newtons
e.9.6 × 103 newtons

Option (c) is the correct answer.

Explanation:

Force is defined as the product of mass and acceleration.

Mathematically,       F =

where           m = mass

                     a = acceleration

Since, it is given that mass of car is kg and acceleration is 4.5 .

Therefore, calculate the net force as follows.

                         F =

                            =  

                            = newtons

Thus, we can conclude that the net force on the car is newtons.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
